Enough people asked me to pass on anything I might learn that I think
it's reasonable to post the most informative answers.  As many people
pointed out, X assumes certain semantics for mem_batchrop that aren't
provided by the pixrect implementation on Suns, and that cannot be 
faked as easily on a 3/110C as on a 3/160C.  

I did receive two replies claiming to have fixed X.V10R4 for true color
operation on the 3/110C.  There are reproduced below; I hope neither of
the principles or organizations involved minds my reposting them.

Hopefully we'll either see Jim Mayer's changes posted soon, or Sun will
allow Bob Searfus to distribute his fixes.
